We remove the gearbox from the engine, removing the input shaft from the hub of the driven clutch disc.
When removing and installing the gearbox, do not rest the gearbox input shaft on the clutch diaphragm spring petals to avoid damaging them.
Before installing the gearbox, apply a thin layer of CV joint-4 grease to the splined end of the input shaft.
To facilitate the operation of installing the gearbox, screw two guide pins M12x1.25 mm (with sawn slots for a screwdriver) into the front lower threaded hole of the cylinder block and into the rear upper hole
Insert the gearbox input shaft into the splines of the driven clutch disk and, orienting the gearbox so that the two guide pins fit into the corresponding holes in the clutch housing, and the standard clutch housing pin into the hole in the cylinder block, pushing the gearbox all the way into the cylinder block engine.
Use a screwdriver to unscrew the guide pins from the holes in the cylinder block.
We carry out further assembly operations in reverse order. Fill the gearbox with oil.
